Question

What does anomalous expansion of water mean?

• A. Water behaves like other liquid up to 4 degree centigrade. But below that temperature its density decrease till it is converted to ice.
• B. Water behaves like other liquid up to 4 degree centigrade. But below that temperature its density increases till it is converted to ice.
• C. Water behaves like other liquid up to 4 degree centigrade. But below that temperature its density remains constant till it is converted to ice.
• D. None of the above

Answer 1

The correct option is A Water behaves like other liquid up to 4 degree centigrade. But below that temperature its density decrease till it is converted to ice.

Answer is A

Water shows unusual expansion.When it is cooled from four degree centigrade to zero degree centigrade is known as "anomalous expansion of water." The unusual behavior of water, when it expands below $4^o$ celsius to $0^o$ is called anomalous expansion of water.
